Man accused of stealing personal info at UTHSC

Matt Stalker was arrested on suspicion of breach of computer security.

Log-on information for personal email, social media sites and at least one financial website may have been compromised by a keylogging device discovered on a public computer at the UT Health Science Center library.

A UTHSC employee discovered the device in the rear USB port of a computer in the Dolph Briscoe Jr. Library on Feb. 1, police said.

Matt Stalker, 49, was seen Feb. 2 checking the rear of the computer where the keylogger had been installed, according to an arrest warrant affidavit.

Using the keylogger's serial number, detectives confirmed he bought the device in January 2010.

Police arrested Stalker on Thursday on suspicion of breach of computer security, a second-degree felony.

An examination of the keylogging device revealed a file containing users' keystrokes, including the log-on information used to access their personal accounts.

UT System Police Chief Michael Parks said authorities are looking into whether more users may have been affected.

“The investigation is very much in the early stages, and the full impact of just how many people have been impacted is still unknown at this time,” Parks said.

Stalker was booked into Bexar County Jail on Thursday night and was released less than an hour later after posting $20,000 bail.
